Onderwerp: 15-STABLE: dhclient fails on em0 (Lenovo T580)

I recently switched from FreeBSD 14-STABLE to 15-STABLE (after branching of 16-CURRENT)
on my working laptop, physically a Lenovo T580. Its LAN NIC FreeBSD recognizes as em0
(see below). System is at: 15.0-STABLE #16 stable/15-n281349-b903f27e171b: Fri Nov 28
05:20:32 CET 2025 amd64. Kernel config: GENERIC.
Configuration has been setup and renewed acording to changes, consider the system as a
fresh install.

Problem: em0 never gets an IPv4 via DHCP on startup (init process via rc.conf).

Configured in /etc/src.conf:
[... WORKAROUND ...]
netwait_enable="NO"
netwait_if="em0"
[...]

and on a regular basis:
[...]
ifconfig_em0="DHCP"
ifconfig_em0_ipv6="inet6 accept_rtadv -ifdisabled nud -no_radr auto_linklocal"
[...]

Very strange: after a final boot up, its very easy to require and achive an IPv4 with

dhclient em0

I'm out of ideas ...
